TYPE-WRITING-MACHINE CUSHION-KEY.

SPECIFICATION forming part of Letters Patent No. 569,196, dated October13-, 1896.

Application filed April 21, 1894.

To all whom it may concern."

Be it known that we, ROBERT SYLVESTER GRAHAM and WILLIAM BENJAMINSAVELL, citizens of the United States, and residents of Newark, in thecounty of Essex and State of New Jersey, have invented certain new anduseful Improvements in Cushioned Keys for Type-Writing or otherMachines, of which the following is a specification.

In the accompanying drawings one form is shown in Figure 1, which is asection of the cushion detached. Fig. 2 is a section of the same appliedto the key, and Fig. 3 a plan of the same applied to the key. Anotherform is shown in Fig. 4., which is a section of the cushion applied tothe key; and Fig. 5 is a plan of the same. Another form is shown in Fig.6, which is a section of the cushion detached. Fig. 7 is a section ofthe same applied to the key, and Fig. 8 a side view of the key detached.

In the form shown in Figs. 1, 2, and 3 the cushion consists of thesoft-rubber band (shown detached in Fig. 1) consisting of thecylindrical body a,having an inwardly-turned bead b at the top. The bodyais made of lesser diameter and longer than the key 0, so that when itis stretched over the key a, as shown in Fig. 2, its elasticity willcarry its lower edge under the key, as shown at cl. In use the finger ofthe operator will strike upon the flange b, overlying the top of 'thekey, which flange b will constitute the cushion. The opening b willserve to expose the top of the key and display the letter, if any therebe thereon.

The form shown in Figs. 4 and 5 is of the same construction as that justdescribed, with the addition of an external band or ringof comparativelyrigid material e, to be fitted over the body a and more securely hold itin place.

In the form shown in Figs. 6, 7, and 8 the cushion consists of the bodya and the flange b, as before, but the body a is shorter than the keyand is secured thereto by springing the lower portion cl into a groovef, formed on the periphery of the key 0. Figs. 6 and 7 also show amodified form for the flange b, which may be used to advantage forincreas- Seria1No.508,496. (No model.)

2. A cushion attachment for type-writer and similar keys having itsupper portion extended over the top of the key and open at its center toexpose the character on the key.

3. A cushion attachment for type-Writer and similar keys formed ofyielding material and constructed to expose the underlying character onthe key.

4. A cushion attachment for type-Writer and similar keys extended overthe key to form a yielding touch-surface said cushion being open at itscenter to expose the character on the key.

5. A cushion attachment for type-writer and similar keys consisting ofan elastic band to be fitted over the key and extended over the plane ofthe top thereof and having asight-opening to expose the character on thekey.

6. A cushion attachment for type-writer and similar keys having itsupper edge curved inward to form a cushion-roll and leave an opencenter.

7. A cushion attachment for type-writer and similar keys having an opencenter to expose the character on the key beneath and a cushion-rollbounding the walls of said opening.

8. A key-cushion consisting of a soft-rubber cylinder having an inwardlyturned flange at the top leaving an opening for exposing the top of thekey.

9. In combination with a key, a soft-rubber cylinder of lesser diameterthan the key, and having, when applied to the key, a lip or flangeextending inwardly on top of the key and leaving an opening to exposethe top of the key.
